 ===== Basics ===== ===== Basics =====
 +The first thing to note is that using the plugboard generally takes a little personal effort. There are sample scripts available to help get you going, but it is assumed that you can prepare a script, get it onto the HAH and run it. Being familiar with tools such as FTP & vi, together with a basic knowledge of some Unix commands will make your work with the plugboard a lot easier. Familiarity of how [[http://www.xapautomation.org/index.php?title=Getting_started|xAP]] works will help too. The extension library has been designed to do much of the 'hard work' for you. Best of all, once you get the basic knowledge under your belt, there is a whole world of possibility for rule based processing and actioning.

 In its most simplistic form a basic application would look like this; It wouldn't do much except send a heartbeat every minute but it's functional. In its most simplistic form a basic application would look like this; It wouldn't do much except send a heartbeat every minute but it's functional.

 When building plugboard applets these calls won't need to be made as the plugboard engine will take care of it.  They will be needed if writing standalone Lua applications something you'll do whilst in development/testing mode.  More on writing Applets later. When building plugboard applets these calls won't need to be made as the plugboard engine will take care of it.  They will be needed if writing standalone Lua applications something you'll do whilst in development/testing mode.  More on writing Applets later.
